This isn’t about adding motors to all-electric vehicles but making car batteries a place for storing home power. This makes the car more than a car. Three key points:

2. Homeowners will be able to run their refrigerators and other essential electrical appliances from those batteries.
3. Homeowners with solar can store off-peak power there or sell their storage capacity into the grid.
